Bio Barrier Root Control System
All three... Biobarrier, Biobarrier II and Biobarrier II Tree Skirt products are made of a durable, nonwoven, polypropylene geotextile fabric with permanently attached nodules containing trifluralin. Trifluralin prevents root tip cells from dividing, which is the method by which roots grow. The nodules are engineered to slowly release the trifluralin, creating a zone where root growth is inhibited. The geotextile fabric is porous to allow air, nutrients and water through it so that soil hydrology can continue to be healthy.
